What's going up and coming down at Marshall Space Flight Center? (photo gallery)

HUNTSVILLE, Alabama - NASA's Marshall Space Flight Center is changing by using a "repair by replacement" strategy on some
of its buildings and a straightforward teardown plan for others. Of its current 4.6
million square feet in facilities, it tore down 270,000 square feet from 2000 to 2012 and will take down another 360,000
square feet this year. The center will take down another 300,000 square
feet by 2019.

1. Building 4471. This sprawling World War II-era building was the home of the
Keller car company and home of a munitions plant turned NASA
laboratory. It comes down this summer.

2. Building 4481. Another big World War II era building, 4481 has held different NASA labs through the years. It also comes down this year.

3. Building 4202. A part of the headquarters complex on Rideout Road.

GOING UP

1. Building 4220, the program office for the Space Launch System (now underway). It will replace current headquarters complex Building 4202. The cost of this project is $39 million including construction, demolition and outfitting. Refurbishing 4202 would cost $75 million, largely because of the cost of asbestos abatement.

2. Building 4221. It will replace Building 4201.

3. A service park on Martin Road near the 4600 office complex containing a gas station and food vendors for NASA employees.
